Tell us what’s happening:

It’s a very strange question. Questions 5, 6 and 7 can’t be passed at the same time. It seems that he only accepts the value of the last result at a time. When my final result is “2000 is a leap year.” I can pass 6, but I can’t pass 5 and 7, and so can the other two.

Your code so far

function isLeapYear(n)
{
  if(n%4==0&&n%100!=0||n%400==0)
    return year+" is a leap year.";
  else return year+" is not a leap year.";
}

let year,result;

year=2024;
result = isLeapYear(year);
console.log(result);

year = 2000;
result = isLeapYear(year);
console.log(result);

year = 1900;
result = isLeapYear(year);
console.log(result);

Welcome to the forum @xiaojiangddz

Check which variables your function is returning.

Happy coding
